Right, now for some proof that this only opens debug packages.
Picture 1)
Making a package using the program, config and edata
You must login or register to view this content.
Successful in making a package file:
You must login or register to view this content.
Unpackaging the created package using the program works:
You must login or register to view this content.
Note no need for a + or - in this case
Now trying the same with the Modern Warfare patch:
You must login or register to view this content.
This program is made for
DEBUG PACKAGES ONLY, the simple fact the patch has a different naming convention (extra sections on the end of the regular pattern) shows something else was done to it after it was made in this program (like being signed by Sony), hence the program cannot 'unpackage' the contents.
And yes, I have tried making my own mw2 patch, and further proof of this being a debug only program is that when the custom made patch goes to install on the ps3 it gives an error, which when searched for, tells me I am trying to install a debug package on a retail machine....
Case closed as far as I can tell here.
